| Along with the popularization of the digital smart devices and network communication technology, digital home network already begins to rise up luxuriantly in China and become a sunrise industry. How to build an integratedinternetwork inside home among increasing number of electronic information devices, has already become an importance research field about digital home network at home and abroad. The arising of IGRS protocolis just about to solve the problem. As the most development potential part of digital home network service, the research and progress levelof multimedia sharing has great significance. A home multimedia sharing system, which is simple and convenient, rich in content, and also adopt a brand new communication mode, will vastly motivate the using interest among users, specific applications such as audio/video push, photos sharing, cultural exchange, health consultation, online education can be implemented upon the multimedia sharing system, that can satisfy the requirement of high quality home life to users. According to this requirement point, the thesis makes a combination of IGRS protocol and multimedia sharing to design a system.This thesis analyzes the IGRS protocol, then designs and realizes a multimedia sharing system which applies to home network. The goal of system is to make different information equipments become automatic connection and resource sharing inside the home network. According to the system design requirements, there can reduce the main research contents as follow:1. The structural design of multimedia sharing system, it includes a centre node and several terminal devices. The system adopts the IGRS protocol to realize the networking between different devices, share the multimedia resource, and can extend to remote user.2. Introduce a centre node as the unified management platform in home network, this centre node is based on IGRS AV application framework, it can be seen as a server in system, manages all the devices and their multimedia resource.It also can undertake the function of control point.3. A media player which is suitable forhome network, the player joins the home network automatically, possesses obtaining and playing multimedia file in home network, controls by centre node acceptably.4. The corresponding module’s function of system has been tested between PC and embedded platform Tiny210V2, the centre node based on PC, the media player based on Tiny210V2. The test procedure mainly aims atdevice’s automatic connection and resource sharing.The test result shows that the design requirements of multimedia sharing system has implemented, and has the characteristics of transmissing and playing high-definition format media file.The system adoptsmature theory and reasonable technology, and a simple and easy of use, interactive multimedia sharing system has been designed, there will have a nice application prospect. |
